Baby Geniuses?

After watching the BBC video about the search for consciousness I was interested most in the part about the age at which we gain consciousness. As stated, it's estimated to be around 18-24 months.
What I find most interesting is the idea that adult people cannot recall memories before an estimated age, usually 3 years old, also called Childhood (or Infantile) Amnesia.

However, other research may suggest that this threshold of early memory may be closer to 2 years, or 24 months of age. This made me question if there might be a relationship between this "gaining consciousness" or becoming self-aware and the ability to learn things that can be remembered years later.

This is supposedly caused by the underdevelopment of the limbic system in the brain, including the hippocampus and amygdala. However, have you ever heard of someone claiming to remember something from before they were 2-3 years old? I know I have.

So, I tried finding research into the idea, and found some call Infantile Amnesia a myth, after some research has apparently found 3-day-old infants able to distinguish a passage from Dr. Seuss' "A Cat in the Hat," after it had been read to them while in the womb! This seems to suggest that it would be very unlikely that this "Infantile Amnesia" could be explained solely by the immaturity of some cognitive systems.

This makes me wonder quite a few things:
When are first able to remember things?
How are we able to recall early memories?
Why are some people able to remember events from their infant years while others can't remember before age 3?

This made me remember a movie, Baby Geniuses (which I probably watched when I was around 8, but remember quite vividly), in which a group of babies were able to not only communicate effectively but accomplish extraordinary things until they hit an age, (around 24 months?) at which they simply "cross-over," as if to another world, no longer able to connect with the other babies.

Is there a connection between childhood amnesia and becoming self-aware?

What is your earliest memory? How old were you?

I don't know much about this, but it makes sense to me that childhood amnesia would be connected to self-awareness. The chapter on memory talks a little bit about this - schemas, or frames of reference, are a big part of how we compartmentalize data in our brains. So if you have no reference point for what's going on, it's harder to form memories. This doesn't rule out the possibility of remembering things outside of this framework, though, so perhaps it is possible.

My first memory is of getting eyedrops put into my eyes, and trying really hard to squeeze them shut. It's in a living room I don't recognize. My parents said I had pinkeye when I was two, and we lived in a house that we moved out of shortly after, so that's my best guess at what the memory was of. My memory has been pretty bad for most of my life, though, so I'm curious as to whether remembering early-stage stuff is correlated with memory abilities once the brain is more developed.

Interesting post Shawna. I had always believed that infant amnesia occurred because those events occur before a child has developed the ability to use language. Without words, it may be more difficult to encode memories in ways that make them easily retrievable.

That is not to say that memory systems don't work. Clearly the evidence you cite show that memory is working, but again certain conditions need to occur for recall such as the child being in the same place where the memory was encoded.

Recent evidence on memory shows that it the strength of a memory is not only about how well it is encoded but also about how often it is retrieved from storage and used in working memory. This is why you remember information from classes the more you talk and write about them.

I find that I never really know about a subject until I teach it. My memory for details improves the more I have to lecture about them.

Nevertheless, my earliest memory is when I was sitting in a blow up pool with my sister at Grandma's house. I was about 2 years old and could probably say a few things by then. There were also photos of the moment which I have seen and likely contribute to my overall memory.

My first blog was on a similar topic as this. I to found it interesting that people could not recall memories until 18-24 months of age. Does this just mean that the first two years of our life our lost to us forever? Also if this was the case how would we remember what was right or wrong before the age of 2? It seems that childrem much younger than 2 know when they are doing something wrong and how would they know this if they did not remember being punished for it before? My first memory was when I was about 3 years old on a plane to Arizona with the Chicken Pox.

I think there may be a connection between self awareness and being able to remember early memories, but I think there may be more to it. While we are young, we have not yet learned the importance of many things. When we do not see the value in remembering things, we often make no effort to remember them. Very few things from birth to the age of 4 seem very important. While I think the lack of self-awareness may contribute, I also thing importance of events also contributes.

I also believe that while we are young, our minds think differently. If we cannot think like we did when we we're three years old, it may be very difficult to remember something from that age. You often had no words to tag an event with, so it was hard to think about. It was confusing.

As for my first memory, I remember going to a dog race when I was about 4 years old. I don't really remember much before then. I'll vaguely remember things here and there, but the first vivid memory I have is of the dog race. My older brother wanted the #7 dog to win, and it was wearing green.

I too struggle to recall events before 3. I can see a traumatic event, such as an injury or a significant scare leaving a lasting memory. But its amazing for someone to recall subtle everyday events before the age of 3.
